I.2 }IODEL 3OO ELECTRONIC CALCULATOR
The \Íode1 300 Calculator is the basic model
in the 300 Series. Operational capabilities in-
clude addition, subtraction, multiplication,
chain multiplications, divisions, reciprocals,
percentages, automatic extensions, weighted
averages. etc. Two independent adders, one on
each side of the keyboard, provide storage and
recall capability. Accumulating switches are
provided for automatic accumulation of entries
and / or multipliers in the dght adder, and pro-
duct or extension accumulations in the left
adder.
All operations, as well as number and deci-
mal input, are initiated by the keys on the key-
board. Display is provided by 5/6 in. high glare-
tiee indicator tubes that display the readout
in conventional form (algebraic sign and nu-
merical value with properly positioned deci-
mal point). t_2
A "clear display" key enables the user to
clear the display without destructing the con-
tents ol the accumulators, etc. A "clear all"
key is provided to clear the accumulators and
